The following explains the impregnated paper production process


The production and processing of impregnated paper is divided into six stages: preparation in advance, humidification, prepreg, dispensing, dry manic and post-treatment process. Everyone in the processing process, in the treatment of static electricity, moisture content, glue amount, wind, drying temperature, refrigeration environment temperature, storage stage, storage cleaning, operator transport and other stages are strictly controlled. Impregnated paper on the original paper and epoxy resin have higher requirements, in the glue link, epoxy resin after improvement with elastic, can prevent surface brittle crack. Epoxy resin should be added with epoxy curing agent, release agent and other additives, the percentage should be suitable, which requires the actual operation of professional and technical personnel with high technical strength and serious and meticulous work attitude can be, otherwise, which stage problems, will cause waste.

Several elements of pre curing degree of melamine impregnated paper:

In the production process of melamine impregnated paper manufacturers, it is very important to manipulate the upper mold clamping force and volatile index, and in addition, it is necessary to pay attention to the factor of pre-curing degree.

The key lies in the volatile matter and the co-molding force. Under the condition that the upper mold force is unchanged, the larger the volatile matter, the smaller the pre-curing degree. However, under the condition that the volatile matter is unchanged, the larger the co-molding force, the larger the pre-curing degree index. Secondly, the positive correlation between the oven temperature and wind, and the influence of ambient temperature on the pre-curing degree, and the wind size of the drying box circulation system will also affect the pre-curing degree index. Once again, water permeability, if the original paper penetration characteristics are weak, epoxy resin glue will also produce a lot of hidden in the surface of the gummed paper paper, and did not penetrate into the base paper fiber, to dry the link will often cause a lot of bubble.

Another factor is the solidification time of the glue. In the production of different types of impregnated paper, the solidification time of the resin glue is different, and the curing level in the drying process is also different, so the pre-curing degree detected is also different.

Rapid Development of Melamine Impregnated Paper

Melamine impregnated adhesive film paper is widely used in customized furniture at this stage, most of which are said to be low voltage and short cycle mode, while under ultra-high pressure and high temperature, it takes tens of seconds to compact the board. In recent years, impregnated rubber film paper is combined with thick steel plate and wood texture to produce the same rent of plant board, which is loved by everyone for its excellent three-dimensional layering. Melamine impregnated paper will form a plate of repair capacity under long-term compaction at low temperature, and is developed and designed by many companies at this stage.

Melamine impregnated paper use experience

1. Beautiful and generous raw material appearance actual effect, enhance practical value. 2. Improve process performance and expand the scope of application. 3. Enhance the use value of artificial sheet. 4. Simplify the production and processing technology of artificial board (prevent spraying, brushing and other processes). With the lack of people's wood resources and the increasing demand of human pursuit of perfect wooden furniture, melamine impregnated paper will also get a better development trend in the 21st century.

okay, thank you all for watching, let's see you next time.

Introduction to the advantages of impregnated paper, come and collect!

Melamine impregnated paper is divided into three categories: plain paper, printing paper and wear-resistant paper. According to the product application, it can be divided into two categories: face paper and base paper. Ordinary paper is different from original color paper and printing paper. The base paper is good, pure in color, not easy to change color, and the color of printing paper is relatively uneven. Generally, plain printing paper is used as base paper (multi-purpose laminate flooring, also called balance paper), which is widely used in cabinets and laminate flooring.

What is the development history of melamine impregnated paper? Let's take a brief analysis. Melamine impregnated paper is generally used for panel furniture, most of which are low-pressure and short-cycle forms, that is, the board is made by pressing for tens of seconds under high temperature and high pressure. In recent years, the synchronous disk produced by combining gelatin paper with steel plate and wood grain has been loved by people because of its good body texture.

What are the main indicators of melamine impregnated paper? Let's make a brief analysis together. 1. The amount of glue: the solid resin content of the decorative film paper (expressed as a percentage (%)). 2. Volatile content: the content (percentage (%)) of volatiles (mostly moisture and other small molecules) on decorative film paper. 3. Pre-curing degree: The curing degree of the resin is expressed as a percentage (%) on the decorative film paper.
